It takes quite a bit for a dream to wake me or for it to be considered bad. But after I had moved a lot of my home town friends started to use meth, and I hadn't talked to them for a few months, and started having dreams that my friends were turining into "zombies, and vampires" first couple of them I put off as just being crappy dreams but then I called my one friend to find out what was going on back in my home town, and found out that they were using dope, becoming vampires staying up all night from the crank, and slowly becomming the living dead.... luckly most 95 % of them have stopped using and have ceased being dope heads.
Also I had another dream that was odd, that the mountains that I lived by were cumbling and I was there to hold them back while my family moved was oblivious. Two or three days later my grandmother (fathers mother) passed away. It was odd enough that it woke me from my sleep.
